That helped, thank you! Was able to make it work using your example. I wonder about the efficiency of Base64. Believe general calculus says a Base64 image is roughly 1/3rd larger than a .png for example. So it will increase storage and bandwidth fees. Perhaps the answer is to render it in Base64 then use something like Element To PNG plugin to convert that to a PNG and save it to DB.

Ideal would be just render as a png but I recognize that may not be straightforward using the TU codebase.

Thanks for your help!
